I have two types, bought from two different vendors.
The red + blue LED is a strip light, approximately 12" long and 2" wide. They are 11w units and their item number is LH-G111WWP. These are also water-proof units, the only practical water-proof units I could find. I wanted to hang them under the top shelf of a two-shelf unit, casting light on four trays of "baby" orchids. That's why I needed them to be water-proof. They are expensive lights! I purchased the four from LEDgrowlight-hydro.com. I don't remember what their lumen output is.
I also have two LED flood-type lights that simply screw into a socket. Their spectrum is white, not red/blue. They were purchased on Amazon and the name of them is Miracle LED 605038 Commercial Hydroponic Ultra Grow Lite. You could not use these in a wet enviornment. They each cost 1/10 of what the strip-lights cost, about $11.00 each. These are 5w bulbs and produce 500 lumens.
